Giving money to open source projects on which you rely on for your business is good practice. While I’ve just now heard about DHH and his political views, I think it is important that the overall mission is to make Linux (and open source software) a mainstream alternative to proprietary solutions. As long as this is not hurting the mission I am personally fine with some unusual partnerships. The alternative is a world where Windows and macOS rule the world.

Additionally open source has always been about stepping up, so contributing or throwing money the other way are always an option. I personally donate to many projects I use. I mostly feel that my political views align with them.
